SPECIFICATION forming part of Letters Patent No. 695,179, dated March 11, 1902!.

Application filed July 13,1901. Serial No. 68,139. (No model.)

To all whom it may concern:

Be it known that we, GEORGE W. STAF- FORD, residing at Providence, and STEPHEN M. HAMBLIN, residing at Central Falls, in the county of Providence, State of Rhode Island, citizens of the United States, have invented a certain new and useful Improvement in Spinning-Spindles, of which the following is a specification, reference being had therein tothe accompanying drawings.

The invention has relation to spinning appliances of that class in which the spinning is effected by means of a rotating whirl part permanently combined with a suitable bearing provided on one of the rails of a spinningframe and a skewer taking the place of the usual spindle-blade and on which the yarn is received as spun applied to the said whirl part and remaining connected therewith during the spinning operation, the said skewer being detached from the rotating whirl part when the yarn-load has been completed and usually being placed directly into a shuttle for weaving, it taking in the latter the place of the usual spindle.

Detachable skewers, such as have just been referred to, have been made of wood in practice, which material is preferable to others for various reasons. Difficulty has been experienced, however, resulting from the tendency of the woodenskewer to warp. The warping has had the effect of destroying the balance of the skewer, so that during operation vibration of the rotating whirl part relative to its bearing has occurred. Variations in the density of the material of which the skewer is formed at different points relative to the center of the skewer and irregularity in the distribution ofthe weight of the yarn-load, &c., have also been found to produce a want of balance, with resulting vibration, chattering, doc.

The object of our invention is to obviate tendency to vibration resulting from want of balance of the skewer or its load thereon. WVc accomplish this object by mounting the whirl part so as to render the same free to adjust itself to an unbalanced load while running.

The invention admits of being carried into effect in different ways.

One embodiment of the invention is illustrated in the accompanying'drawi'n gs,to which reference will now be had.

In the drawings, Figure 1 is a view, mainly in vertical section, showing portion of the spindle-rail of a spinning-frame, a spinning arrangement of the class aforesaid, and a bearing embodying the invention. an elevation of the skewer detached.

Having reference to the drawings, 1 designates part of the spindle-rail of a spinningframe; 2, a bearing applied thereto; 3, the rotating whirl part of a spindle, such as aforesaid, and at the detachable skewer. For the connection of the skewer ewith the rotatable whirl part 3 the latter is shown proyided with a socket 5, which receives the lower end of the skewer, the said socket being in the pres ent ease tapered in order to make good fric tional contact with the lower end of the skewer when said end is entered into the same. The bearing 2 is formed with an elon= gated cylindrical chamber 6, within which the lower portion or body of the whirl part 3 is received and rotates. The diameter of the said chamber is somewhat greater than that of the lower portion or body of the whirl part. The bod y of the rotating whirl part 3is formed with a chamber 7, extending upwardly from its lower end. I

Centrally of the chamber (3 of the bearing -2 is located a vertical pin 8, extending upward through the bottom of the shell of the bearing. Upon this pin is fitted the shell or thimble 9, the upper end of which is closed and rounded exteriorly. The inner end of the bore of the said shell or thimble constitutes a seat which receives the tip or upper end of the said pin. The upper end of the chamber 7 is shaped to constitute a seat which fits the rounded upper end of the shell or thimble 9 and makes bearing contact therewith. Thereby vertical support is afforded to the whirl part. The shell or thimble 9 fits loosely within the chamber 7 of the whirl part, the diameter of the said chamber being enough greater than that of the shell or thimble to aiford opportunity for the whirl part in rotating to move laterally to the extent required for attaining steadiness and quiet ro tation.

Fig. 2 is- To permit escape of air as the whirl part is being placed in position upon the shell or thimble 9, a hole 10 is formed through the said whirl part, communicating with the upper end of the chamber 7. The inflow of air through this hole when the whirl part is lifted oif the shell or thimble relieves the suction tending to raise and retain oil within the chamber of the whirl part.

Various other constructions may be adopted in securing the results aimed at by our invention withoutinvolving a departure from the spirit of the latter.

We claim as our invention 1. In combination, in a spinning-machine, the rotating whirl part, the skewer on which the yarn is received as spun, applied to the said Whirl part, remaining connected therewith during the spinning operation, and adapted to be detached therefrom when the said yarn-load has been completed, and the bearing for said whirl part, constructed to permit the latter to move in adjusting itself to an unbalanced load.

2. In combination, in a spinning-machine, the rotating whirl part having the chamber 7 in the lower portion or body thereof, the skewer on which the yarn is received as spun, applied to the said Whirl part, remaining connected therewith during the spinning operation, and adapted to be detached therefrom when the said yarn-load has been completed, and the upright support loosely fitting within the said chamber.

In testimony whereof we affix our signatures in presence of two witnesses.
